Abstract: A sheet metal hole cutter has a cap plate defining a substantially circular peripheral groove and an annular shelf extending radially outwardly from the peripheral groove. An elongated band forming an approximately circular shape with opposite ends of the band contacting each other defines a base edge received within the circular peripheral groove in an abutting relationship with an inner edge of the groove. The band defines an axial depth of about ½ of an inch or less, and an outer diameter within the range of about {fraction (9/16)} of an inch through about 6 inches. A weld region fixedly secures the base edge of the band to the cap plate. The annular shelf of the cap plate extends radially outwardly from the base edge of the band and defines a radial depth of at least approximately {fraction (1/16)} of an inch in order to prevent over-feeding of the hole cutter through a work piece. A plurality of teeth are disposed along a cutting edge of the band, and each tooth defines a cutting surface extending between an outer edge and an inner edge of the tooth. Each cutting surface is oriented at an acute angle relative to the plane of the cap plate such that the outer edge of the respective tooth is spaced further away from the cap plate than the inner edge to thereby preferentially cut the work piece with the outer edge and create a substantially burr-free hole in the work piece.

Abstract: A coolable blade (10) essentially comprises a blade root (11) and a blade body (1), which is composed of a pressure-side wall (6) and a suction-side wall (5). They are connected to one another essentially via a trailing-edge region (4) and a leading-edge region (3) in such a way that at least one hollow space (2) used as a cooling-fluid passage is formed. An essentially radially running, diverging cooling passage (7) is arranged in the trailing-edge region (4).

Abstract: An ice hockey skate blade has a top edge, a skating edge, and a toe portion. The skating edge has a gliding portion behind the toe portion. The gliding portion width is less than the top edge of the blade and the toe portion of the blade. The front toe portion of the blade allows contact with the ice and has a width equivalent to standard hockey ice skate widths, while the gliding portion of the blade behind the toe section has a width corresponding to ice skate racing blades.
